and acid addition salts and metal salt complexes thereof.

A large number of the substances according to the invention contain one or more asymmetrically substituted carbon atoms. They can therefore be obtained in the form of optical isomers. The present invention relates both to the individual isomers and to mixtures thereof.

Furthermore, it has been found that thiocyanato-triazolyl derivatives of the formula (I) and their acid addition salts and metal salt complexes are obtained when mercapto-triazoles of the formula ##STR13## in which R¹ is as defined above

are reacted with cyanogen chloride of the formula

    Cl--CN                                                     (111)

in the presence of a diluent,

and, if appropriate, an acid or a metal salt is subsequently added to the resulting compounds of the formula (I).

Finally, it has been found that the novel thiocyanato-triazolyl derivatives of the formula (I) and their acid addition salts and metal salt complexes have very good microbicidal properties and can be employed both in crop protection and in the protection of materials for controlling undesirable microorganisms.

Surprisingly, the substances according to the invention have better microbicidal activity, in particular fungicidal activity, than those compounds of the same direction of action which are most similar constitutionally.

The formula (1) provides a general definition of the thiocyanato-triazolyl derivatives according to the invention.

The mercapto-triazoles required as starting materials for preparing the substances according to the invention can be present in the "mercapto" form of formula ##STR36## or in the tautomeric "thiono" form of the formula ##STR37## It cannot therefore be excluded that some or all of the substances according to the invention are derived from the "thiono" form of the formula (IIa). This means that the substances according to the invention are present either as substances of the formula ##STR38## ("mercapto" form) or of the formula ##STR39## ("thiono" form) or as mixtures of substances of the formulae (I) and (la). For the sake of simplicity, only the structure of the "mercapto" form is given in each case.

Using 2-(1-chloro-cyclopropyl)-1-(2-chloro-phenyl)-3-(5-mercapto-1,2,4-triazol-1-yl)-propan-2-ol as starting material and freshly prepared cyanogen chloride as reaction component, the course of the process according to the invention can be illustrated by the equation below. ##STR296## The formula (II) provides a general definition of the mercapto-triazoles required as starting materials for carrying out the process according to the invention. In this formula, R¹ preferably has those meanings which have already been mentioned in connection with the description of the substances of the formula (I) according to the invention as being preferred for this radical.

Some of the mercapto-triazoles of the formula (II) are known. They can be prepared by reacting triazoles of the formula ##STR297## in which R¹ is as defined above,

either

α) successively with strong bases and sulphur in the presence of a diluent, followed by hydrolysis with water, if appropriate in the presence of an acid,

or

β) with sulphur in the presence of a high-boiling diluent, followed by treatment, if appropriate, with water and, if appropriate, with acid.

The formula (IV) provides a general definition of the triazoles required as starting materials for carrying out the process for preparing mercapto-triazoles of the formula (II). In this formula, R¹ preferably has those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred for this radical.

The triazoles of the formula (IV) are known or can be prepared by known methods (cf.

The reaction mixture is initially diluted with ethyl acetate and then extracted repeatedly with saturated aqueous ammonium chloride solution. The organic phase is dried over sodium sulphate and concentrated under reduced pressure. The resulting crude product (1.7 g) is purified by silica gel chromatography using a mixture of petroleum ether and ethyl acetate=1:1 as mobile phase.

Use Examples Example A

Pseudocercosporella herpotrichoides test; W strain (wheat)/protective

Solvent: 1.0 part by weight of N-methyl-pyrolidone

Emulsifier: 0.6 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.

To test for protective activity, young plants are sprayed with the preparation of active compound at the application rate shown.

After the spray coating has dried on, the stem base of the plants is inoculated with spores of the W strain of Pseudocercosporella herpotrichoides.

The plants are placed in a greenhouse at a temperature of about 10° C. and a relative atmospheric humidity of about 80%.

Example B

Pyricularia test (rice)/protective

Solvent: 12.5 parts by weight of acetone

Emulsifier: 0.3 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, and the concentrate is diluted with water and the stated amount of emulsifier to the desired concentration.

To test for protective activity, young rice plants are sprayed with the preparation of active compound until dew-moist. 1 day after the spray coating has dried on, the plants are inoculated with an aqueous spore suspension of Pyricularia oryzae. The plants are subsequently placed in a greenhouse at a relative atmospheric humidity of 100% and at 25° C.

Evaluation is carried out 4 days after the inoculation. 0% means an efficacy which corresponds to that of the control, whereas an efficacy of 100% means that no infection is observed.
